The fixing nut of the windtransducer (Raymarine) has been broken because the previous owner fastened it to tight. I asked Raymarine what kind of synthetic material the nut is made of so I can buy the right glue or welding material to fix the nut. Unfortunately Raymarine (at least the service center guy I e-mailed) doesnot have a clue.

I assume it is PP or PE.

Just buying a new nut seems not possible as it is fixed on the transducer rod (SEE PIC) so it will not possible (I think) to slip it over the rod without disassembling the total transducer. A whole new transducer is also a pricy story?

Any suggestions ?

I have the same problem, but I broke it accidentally did not require power. I did not succeed in gluing parts and I ended up with a black Gorilla tape to keep the parts in place works well.

I'm sure Raymarine planned part of the readily degradable and get you to buy a whole new products ...

I also have an o-ring leaked from the salty spary part of the tip and the gorilla tape keeps it out of the box and in operation.

Experimented with a few glue types on plastic and fail, without even testing the epoxy adhesive ... in a sealed tape

Use Loctite 406. It is amazing on plastics. We use it at work for certain kinds of plastics bonding. In my opinion, that's about your best hope. Keep in mind that even a perfect part broke once, so even the best glue won't be better than original. Even if it is somehow as good as original, it can obviously still break.

How expensive is this sensor? You could make up a print of a replacement part, take it to a machine shop to be made in delrin, cut in half lengthwise, and use screw together features. Make 20 and sell them on the internet!
You will not break delrin.
